Answer:
The velocity is 8.93 meters/second.
Step-by-step explanation:
It is given that Elena runs for 28 seconds and finishes at 250 meters.
Here the displacement is 250 meters and the time is 28 seconds.
We know that 
Substitute displacement = 250 and time = 28 in above formula.

meters/second
Hence, the velocity is 8.93 meters/second.
Well if he made 10 in 4 hours, that means he made 5 in 2 hours. after 2 hours he had 30 cards, so that means he started with 25 cards. Mr. Cringle is making 2 and 1/2 cards per hour.
Answer:
d < 1
Step-by-step explanation:
First, we have to get d on the same side of the equation. So we will subtract d from both sides and the equation will be 12d-d < + 11. We could also write this problem as d(12-1) < 11, which when simplified would be d(11) < 11. Next, divide both sides by 11 and you get d< 1. Hope this helps and have a great day!!:D
